Y By means ofthe adjustability of the member longitudinally ofthe guide rods 12 and 12 Iam enabled to vary the extent of travel of .the carriage without destroying the V'effectiveness of the resilient means which acts as abuffer" at the ends ofthe path of f movement oftlie carriage. 'It is very desiri A able in Vcutting narrow substances such asV sausages and the like, to reduce the extent of the movement of the carriagev so `that Athe stroke Vwill ybe just sufiicient to move the sub- A Vstance clear of the knife on the return movev ment of the carriage, thereby eliminatingany Y extra or unnecessary motion of thecarriage rr'.earriagemay be moved at any desiredfs'peed to effect a vsaving in time and energy.

' rand when cutting substances which 'do' not contain-bones or in cutting substances which do not require agreatamount of pressure lto I bc'exertedon thetable, the bumper construction is'not'utilized to its fullest extent as the "operator can generally gauge his movements so that as soon' astlie cutting stroke is iinishedV the pressurevcan be applied to the carriage in the reverse direction.A However, when slicing substances containing bone, the operator pushes the Vcarriage at rapid rate towardthe vknifeso. that the knife will cut through the bone and sever the bone as well as cut the slice.from the meat; UIn cutting through bone, it is preferable lto `have the knife` strike thel bone witha relatively sharp blow as the bonek ismore readilycut in this 'mannenthan' with a slow slicing movement. The actionH of the knife onthe bone is similar to that of a -meat Cleaver. In cutting s. pork chops if the knifey passes between two soonas the slice is entirely severedifrom the adjacent ribs the 'cutt-ing Yforce required is not as great as if the knifehasto pass through fr the rib itself.V The'operator, however,in

moving: vthe table Ymustapply a suflicient l.amoui'itofi force thereto. to enable Lthe knife lto, cut throughthe rib itself. Therefore, if instead of lpassing through theribit passes through the bone cutting 'adjacent the ribs,

'some;of the-'force exerted on the carriage is notfutilized forfthecutting*stroke and as substancathe carriage continues the Vrapid movement which must be cushionedl in order to prevent damage "to the carriage V'andits bearings. The"excessiforceis utilized to helpreturn the carriage toits original position. QI

It willlbe seenV that the'bumper construction ygei'ierally comprises two elements one ofy which'is stationary and the other of which isV f movable i relative to `the stationary memberv during the time the cushioning means is compressed. vThe movable element-has Va' receiving'the stationary element-.28 tocompressV the vspring 29. V l I claim 2- Y l1. In a slicingmachine havinga slicing knife vand a work support, a slide rod upon which said work support is slidably mounted for reciprocationpast the edge of said knife,

said work' support having oppositely directed 'recesses therein, a'spring in each of said recesses, an abutment 'member against which one end of each spring bears,fstationarycon tactfmembers, said abutmentfi'nembers each n having a contact face adapted to engage one reciprocative movement to compressA said .springs and yieldingly retard the motionof said work support, one of said contact'members being adjustably'mounted -oii said slide of lsaid Contact members at-the end VTof each rod to vary thelengtli ofthe path o-f-reciprocativemovement of said work Support.' y
